Sexually liberal attitudes have been found to relate strongly to sexual behavior, primarily first intercourse, of both males and females. This study focused on sexual attitudes of adolescents aged 14 to 19. The variables considered include: gender, classification, religious affiliation, family type, educational ability, autonomy, and aggression. Because the rates of promiscuity, sexual violence, and teenage pregnancies have increased greatly over the past years, attitudes that may influence these behaviors were explored. This study gathered information that could be used to build better counseling, guidance, and education programs. Students (N=235) from five high schools in the western half of Kansas responded to questionnaires that included demographic information, the Sexual Attitude Scale, and the aggression and autonomy scales from the Edwards Personal Preference Schedule. The results supported the following generalizations: (1) males were more liberal than females; (2) adolescents from the single parent family type were more liberal than adolescents from any other family types; (3) freshmen were more liberal than juniors; (4) males from two parent families were more liberal than females from two parent families; (5) males from the single parent family type were more liberal than females from the same family type; (6) males from other than single parent family types were more liberal than females in this category; and (7) females from the stepfather family type were more liberal than males from the stepfather family type.
